Biography
Odo was the son of Robert II of Burgundy, and he succeeded his brother Hugh V of Burgundy upon his death in 1315. In 1316 he became the titular king of Thessalonica after the death of his brother Louis of Burgundy, but in 1320 he sold these claims to Duke Louis I of Bourbon. From 1337 until his death he was a key player in the Hundred Years' War, choosing to side with Philip VI of France against Edward III of England. He was an adviser to Charles of Blois during the War of the Breton Succession, fighting against Jean IV of Brittany's English-backed forces. He died in 1350.
